Abstract

The invention relates to blister packaging consisting of a cup-shaped upper part (1), configured from a plastic film and comprising an opening (3) that is enclosed by a sealing flange (2), whereby said upper part (1) is designed to house a pelleted product (4) and consisting of a breakable sealing foil (5), which is connected to the sealing flange (2) of the upper part (1) and seals the opening (3). According to the invention, the upper part (1) has a base area (6) lying opposite the opening (3) and a side wall (7) between the base area (6) and said opening (3), said wall flaring at least in sections towards the opening (3). The blister packaging is characterised in that the side wall (7) comprises a first wall section (8), originating and flaring from the base area (6) and opening into a second wall section (9), which does not flare to the same extent as the first wall section (8) and that a continuous buckling line (10) is configured between the wall sections (8, 9), in such a way that when pressure is applied to the base area (6) in the direction of the opening (3), the second wall section (9) of the side wall (7) does not in effect buckle inwards.

Description

Blister packaging

The invention relates to a push-through packaging with the features of the preamble of claim 1 or the features of the preamble of claim 9 and a packaging unit with the features of the preamble of claim 20.

Blister packs of the type in question, which are often also referred to as blister packs, serve in the pharmaceutical, ecotrophological and cosmetic fields as containers for accommodating corresponding products such as capsules, dragees, tablets, active ingredient balls, etc. The lumpy product is located in such a blister pack within the Cup-like upper part, the opening of which is sealed by the sealing film, such as sealing film. The product is thus protected against environmental influences such as moisture and dirt and gives the consumer the guarantee of the durability and original condition of the packaged product.

A push-through packaging of the type in question is described, for example, in EP 0 563 934 A1, further information on the prior art can also be found in the publications DE 299 07 744 U1, DE 29 07 740 U1, DE 43 17 326 C1, DE 91 03 973 U1, US 6 443 307 B1 and WO 98/43893 A1, to name just a few publications.

The design of push-through packaging and the selection of plastic films to form the upper part of sealing films are part of the tools of experts in the field of packaging technology. In general, the "Packaging Handbook 1999", publisher for chemical industry, Augsburg, in particular pages 211 to 213, 388 to 413 to get expelled. There, extensive explanations of the parameters involved, the plastics used, etc. are given.

In push-through packaging of the type in question, the side wall of the cup-shaped upper part, which is formed from plastic film, is preferably conical in shape and, if necessary, adapted to the geometry of the lumpy product which is in the push-through pack. However, this adaptation relates to the shape of the side wall in the plane parallel to the floor area. In the plane perpendicular to it, that is to say, in a vertical section through the push-through packaging, there is no particularly preferred shape, rather the shape is rather production-related or mechanical-dependent, depending on the design of the molding device.

It has been shown that with a push-through packaging filled with a lumpy product, the sealing film is occasionally pressed through, but the lumpy product nevertheless does not leave the receiving space in the upper part, but remains there. This may be due to the fact that the upper part, which is formed from plastic film, deforms in such a way that the opening which serves to discharge the product is reduced.

The teaching is based on the problem of avoiding inadvertent remaining of the lumpy product in a push-through packaging of the type in question by designing the push-through packaging and at the same time to achieve that pressure-sensitive lumpy products can also be handled easily.

The problem outlined above solves the teaching in a push-through packaging with the features of the preamble of claim 1 by realizing the features of the characterizing part of claim 1. A secondary solution describes claim 9. In particular, a combination of the two approaches promises an optimal problem solution. Preferred refinements and developments are the subject of the subclaims.

According to the invention, the upper part of the push-through packaging formed from a plastic film is specifically provided with certain contours to form one or more crease lines, which are designed and arranged in such a way that a narrowing of the opening serving for the exit of the lumpy product is avoided. The weak points in the upper part formed by the crease lines simultaneously reduce the effort required when pushing the bottom area towards the opening, so that even delicate, lumpy products can be optimally dispensed with such push-through packaging.

For the design of the push-through packaging in detail, reference may also be made to the specialist knowledge documented in the "Packaging Manual 1999", which is also applicable in the present case.

The push-through packaging according to the invention is of particular importance in the field of finished cosmetic products, in particular hair colors.

Hair tints and care products too. To this extent, the invention

Push-through packaging in a particularly advantageous manner, the delivery device of a second partial packaging of a packaging unit for an input or

Form multi-component end product (claim 20). Such a packaging unit enables activation by the user in a simple manner

Wise, timed and reproducible and carried out without risk to the user.

First of all, it is essential that the second partial packaging is fixed to the first partial packaging when ready for use. The delivery side of the second partial packaging then at least partially covers an opening of the first partial packaging. The position of the second partial packaging in the ready-to-use state is thus precisely determined, so that the second product component can be dispensed directly into the unlocked opening of the first partial packaging.

When the multi-component end product is activated, the user is thus forced to bring the second partial packaging into the predetermined position on the first partial packaging. This makes the activation process reproducible and safe for the user. Contact of the user with the second product component can be avoided in any case.

Furthermore, it is particularly advantageous that the second partial packaging at least partially covers the opening of the first partial packaging when ready for use. This means that further product components in the ready-to-use state cannot be passed through the opening of the first partial packaging as long as the second partial packaging is fixed to the first partial packaging. In order to be able to add further product components, the second partial packaging must first be detached from the first partial packaging. With a corresponding configuration of the first and the second partial packaging, it can be provided that the detachment of the second partial packaging from the first partial packaging corresponds to a reaction time to be observed, so that the user is forced to adhere to this reaction time.

The second partial packaging can preferably be fixed to the first partial packaging by screwing, plugging, bouncing or the like. In the case of a screw connection, it is particularly advantageous that the time required for the separation of the partial packaging can be controlled by the number of thread turns, preferably in the first partial packaging.

In a special embodiment, the first partial packaging is resealable, preferably by a screw cap. After admitting of a product component in the first partial packaging, the first partial packaging can be closed again, so that mixing by shaking is possible. It is only possible to add further product components after opening the closure. As a result, a further time delay can be controlled depending on the design of the screw cap.

In a particularly preferred embodiment, the second partial packaging has a delivery device for the product component or the product components which, when ready for use, conveys in the direction of the opening of the first partial packaging. In addition to the dispensing device, a reservoir is preferably provided for receiving the product component or the product components, which ensures a portioned dispensing of the product component or the product components. Depending on the design of the reservoir, it can be provided that the user himself selects the dosage of the product component or the product components.

In a particularly preferred embodiment, a flat section is provided for the second partial packaging, which is arranged parallel to the opening of the first partial packaging and which, when ready for use, forms a flat cover over the opening of the first partial packaging and which preferably has the dispensing device. With such a section, on the one hand the addition of a further product component is prevented when the second partial packaging is fixed, on the other hand direct contact of the user with the product component in the second partial packaging is also not possible.

In order to be able to fasten the second partial packaging to the first partial packaging, in a preferred embodiment the second partial packaging has at least one further section which is arranged parallel to the opening of the first partial packaging and which takes over the function of a holder. This holding function is preferably ensured by the sections of the second partial packaging having openings which are located on a projection of the first partial packaging, in particular a bottle neck, are clamped, plugged in or screwed on when ready for use.

The configuration of the second partial packaging is particularly compact and simple to manufacture such that the above-mentioned sections of the second partial packaging are at least partially formed in a box shape - box section.

In the event that the second partial packaging is cut and produced from foldable material, it is provided that at least one edge of the second partial packaging has one or more elongated holes between the section forming the flat cover over the opening and a bent, preferably rectangularly arranged section , In particular, this offers the advantage of easy foldability and, if appropriate, flexibility of the material, in order to prevent the surface of the second partial packaging from tearing open.

If the box section is laterally closed on only two opposite sides, it has a parallelogram structure and can be folded in and out. This is particularly advantageous for the ready-to-sell condition of the packaging unit, since the second partial packaging, when folded, is flat and essentially strip-shaped. This configuration is particularly advantageous if the second partial packaging essentially consists of cardboard.

The push-through packaging according to the invention is advantageously used together with the packaging unit mentioned above as packaging for finished cosmetic products, in particular hair colors, hair tints, care products or the like. In a method for producing a multi-component, at least one further product component from a second partial packaging is to be added to at least one product component in a first partial packaging in order to arrive at the “final” finished product. It is envisaged to place the second partial packaging on the delivery side over an opening of the first partial packaging, to convey the product component from the second partial packaging into the first partial packaging without direct contact with this product component, and finally to mix both product components in the first partial packaging to form the finished product. It is particularly advantageous if the arrangement of the second partial packaging with the partial packaging according to the invention also allows only a dosage of the products from the first partial packaging, so that the user can, depending on the need, via the dosage of a one-component end product or a multi-component end product as a mixture of the can decide the first partial packaging. This is because applications are conceivable in which only components are stored in the second partial packaging which, for example, lead to a higher concentration in the end product. An addition is therefore not absolutely necessary.

The use of the push-through packaging according to the invention in connection with a coloring product as it is also the subject of a parallel patent application by the applicant, patent application 102 08 874.8 "colorant" dated March 1, 2002, is of particular importance. The disclosure content of this patent application is referred to in the disclosure content of the present patent application included.

With regard to the lumpy product in the push-through packaging in connection with coloring products, the disclosure content of the present patent application is finally incorporated by reference into the disclosure content of the applicant's parallel patent application 102 08 875.6 "Shaped bodies with pearlescent pigment", the filing date of which is also March 1, 2002.

There are, of course, a large number of possibilities for developing and developing the teaching of the invention. For this purpose, reference may be made to the subclaims. In the following the invention will now be explained in more detail with reference to exemplary embodiments shown in the drawing. Particularly preferred refinements and developments of the invention, as well as particular advantages of certain refinements, are also dealt with in connection with the explanation of the exemplary embodiments.

Fig. 1 shows in a section the principle of a push-through packaging. This consists of a cup-shaped upper part 1 formed from a plastic film, which can also be a film laminated with a metal coating, with an opening 3 enclosed by an essentially radially outwardly projecting closure flange 2. The upper part 1 serves for receiving a lumpy product 4, which here has a spherical shape, for example an active ingredient bead. The opening 3 of the upper part 1 is closed by a push-through closure film 5 which is connected to the closure flange 2 of the upper part 1 and which is preferably a metal film or a metal / plastic composite film or a burstable plastic film.

1 shows for the push-through packaging of the prior art shown there that the upper part 1 formed from plastic film has the overall shape of a spherical section, that is to say no special structuring of the upper part 1 is provided.

FIG. 2 shows that the upper part 1 has a bottom area 6 opposite the opening 3 and between the bottom area 6 and the opening 3 a slightly widening, at least in some areas, in the direction of the opening 3 Has side wall 7. In the exemplary embodiment in FIG. 1, one could speak of side wall 7 and bottom area 6, although here bottom area 6 and side wall 7 merge into one another without gradations.

In general, it is true that this is a push-through packaging for only one lumpy product 4, but that the teaching of the invention also applies to push-through packaging with a plurality of upper parts 1 arranged next to one another for receiving a lumpy product 4 or possibly also for holding several lumpy products Products 4 stretches. In this respect, reference may also be made to the prior art, which was explained at the beginning, for examples.

2 now shows that the side wall 7 has a first wall section 8, which starts from the base region 6 and widens, and an adjoining wall wall 9, which widens less than the first wall section 8, possibly also does not expand, but is exactly cylindrical and that a circumferential kink line 10 is formed between the wall sections 8, 9 such that when pressure is exerted on the base region 6 in the direction of the opening 3, the second wall section 9 of the side wall 7 does not kink inward. The extent to which the second wall section 9 shifts radially outwards depends on the elasticity of the plastic material of the upper part 1. Basically, the arrangement of the wall sections 8, 9 is made due to the different inclination of the wall sections 8, 9 such that a radially outward force component is introduced from the first wall section 8 into the second wall section 9. It is thereby achieved that the movement space available for the product 4 tends to become larger, not smaller. The product 4 can be caused to emerge unhindered from the opening 3 by pushing the closure film 5 due to the pressure on the bottom area 6. The illustrated embodiment is not true to scale with respect to the line widths, but is understood to be understandable. This also applies to the other images.

The exemplary embodiment shown shows that here both the first wall section 8 and the second wall section 9 expand in the direction of the opening 3 in that they have a conical shape or a conical contour. However, this is not mandatory, even an arcuate course can have a similar effect.

Already in the prior art (EP 0 563 934 A1) it has been pointed out that, in the case of push-through packaging of the type in question, the side wall 7 has a greater wall thickness than the base region 6 due to the manufacturing process, without additional measures. According to the invention, it is now proposed that, according to a preferred embodiment, the push-through packaging is produced in such a way that the second wall section 9 is stiff, in particular stiffer than the first wall section 8. This ensures that the bottom area 6 with the first wall section 8 under axial pressure transmission can be pressed inwards on the lumpy product 4 into the almost cylindrical receiving space ultimately formed by the second wall section 9, without the second wall section 9 collapsing prematurely. This also serves to maintain the movement space for the product 4 and the safe discharge of the product 4 from the opening 3.

3 shows a further exemplary embodiment of a push-through packaging. It is additionally provided here that the second wall section 9 and here also the first wall section 8 are provided with mechanical stiffeners 11, in particular beads, crease lines etc., molded into the plastic material. The mechanical stiffeners 11 can reinforce certain areas of the side wall 7 and weaken other areas of the side wall 7, so that a certain behavior of the Side wall 7 can be realized at pressure in the axial direction on the bottom region 6. In addition, this contouring of the upper part 1 allows some interesting visual and design effects to be achieved.

Special optical effects can be achieved, as shown in FIG. 3 in connection with FIG. 4, in that the stiffeners 11 are arranged overall in the manner of a honeycomb structure or, as here, in the manner of a brilliant cut structure.

The latter design in particular offers particularly interesting design aspects. Here it could be advisable not to design the plastic material of the upper part 1 to be transparent or translucent, but to have a metallic sheen, for example also vapor-coated or laminated, or also to have a pearlescent sheen.

The exemplary embodiments shown in FIGS. 2 and 3 show, moreover, that the base region 6 is flat and merges into the first wall section 8 via a kink line 12.

The design of the stiffeners 11 also makes it possible to implement axially extending buckling lines, as shown here. The distribution of the stiffeners 11 over both wall sections 8, 9 creates the optimal possibility of influencing the behavior of the upper part 1 when pressure is exerted on the floor area 6.

In principle, it is also conceivable that, similar to FIG. 1, the base region 6 merges into the first wall section 8 in an arcuate manner, in particular with the first wall section 8 in a dome-shaped manner. This is not shown here, however. The exemplary embodiments in FIGS. 3 and 4 also show that here the second wall section 9 merges directly into the closure flange 2, forming a kink line 13.

5 and 6 show exemplary embodiments which are designed differently than the exemplary embodiments of the previously described figures. Here, according to the subordinate, an alternative descriptive claim 9 is provided that the side wall 7 at the open edge with the formation of a kink line 14 in an i.w. radially outwardly projecting ring flange 15 merges that the ring flange 15 merges at the radially outer edge into an approximately cylindrical jacket section 16, which merges into the closure flange 2 at its open edge, forming a kink line 17, and that when pressure is directed in the direction of the opening 3 the bottom region 6 of the ring flange 15 kinks inwards and radially outwards.

5 shows, in an enlarged detail, the relationships in the area of the bend line 14 between the side wall 7 and the ring flange 15. The arrow indicates how the area of the bend line 14 is when axially directed pressure is exerted on the bottom area 6 of the upper part 1 shifted downwards and outwards. The connecting arch between the ring flange 15 and the jacket section 16 has the function of a pivot hinge. The arrow makes it clear that the passage opening effective for the product 4 at the level of the bend line 14 tends to increase radially due to the axial pressure on the bottom region 6. Of course, this also depends on the elasticity of the plastic material used. In any case, the direction of the force action is clear.

It can be clearly seen that, according to the preferred teaching, the transition from the ring flange 15 to the jacket section 16 is rounded, that is to say does not form a kink line. This promotes the controlled hinge function of this area. With regard to the jacket section 16, it has already been explained that this is an approximately cylindrical jacket section 16. This cylindrical jacket section 16 makes it possible to insert the push-through packaging as a whole into a circular opening in a holder made of cardboard, for example. This can be an opening in a cardboard strip, which is part of an overall multi-part packaging unit. Due to the manufacturing process, a slightly inclined course of the jacket section 16, which widens slightly towards the opening 3, is readily realized. A precisely cylindrical course is also expedient and producible. The construction is also of interest if, as shown in FIGS. 5 and 6, the jacket section 16 extends slightly widening from the opening 3 to the ring flange 15, which enables a kind of locking in an opening in a cardboard strip.

For the particular field of application of the teaching pharmaceutical, but in particular cosmetic applications, it is advisable to provide a height of 2 to 5 mm, preferably of about 3 to 4 mm, for the jacket section 16, the overall height of the upper part 1 of the blister pack should be 8 to 15 mm.

5 shows an exemplary embodiment of a push-through packaging in which the features of the exemplary embodiment of FIG. 2 are also realized, that is to say the teachings of the two independent claims are combined with one another. 6, 7 accordingly show an exemplary embodiment in which the features of the exemplary embodiment from FIGS. 3 and 4 are also realized. Features of both stakeholder groups are also realized here.

In both exemplary embodiments, the push-through packaging according to the invention is optimally designed and usable. Nevertheless, it should be pointed out that both embodiments can also be implemented side by side and independently of one another. Overall, there are still some interesting areas for the push-through packaging according to the invention with regard to the parameters that can advantageously be realized.

First of all, it is recommended that the thickness of the starting plastic material of the upper part 1 (before deep-drawing) be approximately 150 μm to 600 μm, preferably approximately 400 μm, and approximately 180 μm to 220 μm, preferably approximately 200 μm, at the kinks. In the deep-drawn state, the kinks are thinner, preferably about 30% to 60% thinner than the wall material. In any case, this applies to typical plastic films made of PE, PP, PS, PET; PVC / PVDC, PVC / PFC etc. (see the specialist literature and patents mentioned at the beginning).

It is also recommended that the sealing film 5 is designed as a metal film, as a multilayer film using metal and / or plastic and / or paper, as a burstable plastic film or as a paper film.

There is a wide range with regard to the thickness of the sealing film 5. For metal foils, in particular aluminum foils, there is a preferred range of 15-20 μm. Penetration forces of the sealing film 5 according to DIN 53142 in the range from 10 to 20 N are equally recommended. A typical aluminum composite foil defines a force of 15 N.

The illustrated and preferred embodiment shows the configuration of the lumpy product 4 as a spherical solid (pearl). This is not mandatory, but is particularly useful. For the rest, reference may be made here in particular to the DE 102 08 875.6 already mentioned. It is also possible to store other dosage forms such as gels, paten, granules or liquids, but these must be flowable. The push-through packaging is then equipped with appropriate means which cause the sealing film to break through. Particularly interesting parameter ranges for certain dimensions result from the fact that the lumpy product 4 has a breaking hardness of 50 to 120 N, in particular of at least about 60 N and / or that the lumpy product 4 has a diameter of 5 to 10 mm, in particular from 8 to 9 mm and / or that the lumpy product has a weight of 200 mg to 600 mg, in particular of about 400 mg.

For the formation of various surfaces by stiffeners 11 and kink lines, 6 to 10, preferably 8 surfaces in the first wall section, 16 to 30, preferably 24 surfaces in the second wall section 9 are to be mentioned as examples for the exemplary embodiments shown. For the rest, reference may also be made in detail to the aforementioned DE 102 11 303.3, the disclosure content of which has also been incorporated here by reference.

It has already been pointed out that the push-through packaging claimed is particularly recommended for a lumpy product 4, which is only a component of a multi-component overall product, in particular a finished cosmetic product. In particular, the lumpy product 4 in the push-through packaging according to the invention is a coloring product, in particular the color component of a multicomponent hair dye or hair tinting agent or a component of a hair care product. The push-through packaging according to the invention allows the component to be introduced safely, contactlessly and quickly into the product receiving the component.

The push-through packaging described can be used particularly expediently in conjunction with a packaging unit shown in FIGS. 8 to 11. 8 shows a side view of such a packaging unit for a multi-component end product, which consists of a plurality of separate partial packs 21, 22, with at least one on a first partial pack 21 Product component, a second partial packaging 22 can be fixed with at least one further product component and the second partial packaging 22 with its delivery side 23 for the at least one further product component at least partially covers an opening 24 of the first partial packaging 21. The push-through packaging according to the present patent application can be seen here as a dispensing device 26 in the upper region of the second partial packaging 22.

The packaging unit is not shown ready for sale. For sale, the individual partial packs 21, 2 are arranged in a superordinate pack, in particular a folding box. It should be pointed out that the second partial packaging is not necessarily only defined in the ready-to-use state of the first partial packaging, but it can also be provided that the second partial packaging is already fixed on the first partial packaging in the ready-to-sell state. Then superordinate packaging is omitted and the loss of partial packaging is prevented.

When ready for sale, the first partial packaging 21 has a closed opening 24. The opening 24 can be closed by a screw cap with thread 25 and / or by a film. The second partial packaging 2, which can preferably be detachably attached to the first partial packaging 21, can be fixed in a special embodiment by screwing, plugging, bouncing or the like on the first partial packaging.

It is particularly advantageous if the first partial packaging 21 has a thread 25 onto which the second partial packaging 2 can be screwed. In addition to a robust connection between the second partial packaging 2 and the first partial packaging 21, this also ensures that the time required for the separation of the partial packaging can be controlled by the number of thread turns. This takes into account the fact that in certain cases, certain process-related waiting times must be observed before For example, further product components can be added to the first partial packaging 21.

In a preferred embodiment, the first partial packaging 21 is designed to be resealable. This makes it possible to close and mix by shaking after adding a product component. Depending on the design of the corresponding closure, certain waiting times can in turn be controlled here.

In the exemplary embodiment according to FIGS. 8 and 11, the first partial packaging 21 is bottle-shaped, but other shapes can also be provided.

In the present case, the second partial packaging 2 has a delivery device 26 for the product component or the product components 4, which in the ready-to-use state shown in FIG. 8 conveys in the direction of the opening 24 of the first partial packaging 21. It can be clearly seen that this arrangement of a dispensing device 26 makes it impossible for the user to come into contact with the product component 4 contained in the second partial packaging 2, since the second partial packaging 2 virtually closes the opening 24 of the first partial packaging 21. The delivery of the product component 4 by the delivery device 26 can take place directly into the unlocked opening 24 of the first partial packaging 21.

In the case of the opening 24 of the first partial packaging 21 being closed by a film, it is provided in a further preferred embodiment to pierce the film by means of the dispensing device 26, additional means such as thorns and / or a solid-like product component, so that the product component passes through the opening 24 can be delivered.

The second partial packaging 2 has a reservoir 27 for receiving the product component or the product components. Depending on the design the reservoir 27 ensures a portioned delivery of the product component or the product components tailored to the respective application. For example, it can also be provided that the reservoir 27 is divided into individual reservoirs 27 so that the user can determine the dosage of the product component himself.

It can also be provided that the second partial packaging 2 is designed to be resealable, so that further metering options are available. In addition, depending on the product component, environmentally compatible disposal is possible without chemicals being able to escape from the reservoir 27 in an uncontrolled manner. For example, the second partial packaging 2 can be designed as a blister strip with the above-described push-through packaging with liquid, solid (lumpy, powdery, granular), pasty or gel-like product components individually packed and to be metered therein.

In a further preferred embodiment, it is provided that the second partial packaging 2 has at least one flat section 28 arranged parallel to the opening 24 of the first partial packaging 21, which, as shown in FIG. 8, has a flat cover over the opening 24 in the ready-to-use state forms first partial packaging 21. A dispensing device 26 and possibly a reservoir 27 is now preferably arranged on the above-mentioned section 28 in such a way that it conveys in the direction of the opening 24 of the first partial packaging 21.

For fastening and clearly positioning the second partial packaging 2 on the first partial packaging 21, it is now provided that the second partial packaging 2 has, in addition to the above-mentioned section 28, at least one further section 29, 30 which takes over the function of a holder. For this purpose, the section 29, 30 has an opening 21, 32 which is clamped, plugged in or screwed on to a projection such as the neck of the first partial packaging 21 in the ready-to-use state. The diameter of the Opening 21, 32 is largely arbitrary, provided that this is adapted to the diameter of the projection of the first partial packaging 21. The diameter preferably moves within 20 mm to 30 mm. Depending on the application, additional parallel sections can be provided to support the holding function. A preferred number of sections here are two sections, however up to five sections, in special cases even more sections, can be provided.

A further stabilization of the second partial packaging 22 on the first partial packaging 21 is achieved in that the opening 21, 32 of the section 29, 30, which encloses the opening 24 of the first partial packaging 21 in the manner of a sleeve, is slightly smaller in diameter than the outer diameter of the Opening 24 is. The resultant effect is that the second partial packaging 22 can be applied tightly to the opening 24. If the opening 24 has an external thread 25, there is the additional advantage that, with a corresponding design of the section 29, 30, the second partial packaging 22 engages to a certain extent and, if necessary, there is also an audible snap.

A particularly simple attachment of the second partial packaging 22 to the first partial packaging 21 results from the fact that the openings 21, 32 of the sections 29, 30 of the holder are essentially centered in the ready-to-use state with respect to the opening 24 of the first partial packaging 21.

In a preferred embodiment, the sections 28, 29, 30 of the second partial packaging 22 are essentially box-shaped in the ready-to-use state. In a particularly preferred embodiment, the second partial packaging 22 has three sections 28, 29 30, of which, when ready for use, one section 28 forms a flat cover over the opening 24 of the first partial packaging 21 and two sections 29, 30 form a holder on the first partial packaging 21 , It is further provided that all sections 28, 29, 30 form a box section 34. The box shape of the second Partial packaging 22 leads both to high mechanical stability and to a particularly compact design, as will be shown below.

In a preferred embodiment, the above-mentioned section 28, which forms a flat cover over the opening 24 of the first partial packaging 21, is formed from two parallel layers, preferably from cardboard. In this embodiment, it is advantageous to clamp at least part of the dispensing device 26 between the two layers 28, 28. As a result, further fastening measures for the dispensing device 26, for example gluing the dispensing device 26, can be dispensed with. If, as shown in FIGS. 8 and 9, the box section 34 has a closed structure laterally on only two opposite sides 35, 36, the box section 34 can be set up or folded flat. Here, use has been made of the fact that the second partial packaging 22 "lacks" a carrier component in the non-attached state, so that the second partial packaging 22 can only be stable in the ready-to-use state and is otherwise collapsible. This parallelogram structure of the box section 34 can be seen particularly clearly in the middle representation of FIG. 9.

In a further preferred embodiment, the second partial packaging 22 has an elongated section 37 which fulfills various functions. First of all, it can be used in the sense of a lever for fine alignment of the dispensing device 26 above the opening 24 of the first partial packaging 21. With a suitable design of the elongated section 37, the elongated section 37 can also have a stabilizing effect. Furthermore, the elongated section 37 can be printed with instructions for use, with a company logo or the like. Provision can further be made to provide the necessary warnings or contents, preferably on the back of the elongated section 37. It can also be provided to provide the elongated section 37 with a pocket for receiving instructions for use or the like, which can be inserted into the pocket. With a corresponding design of the elongated section 37, it is possible for the second partial packaging 22 to be essentially strip-shaped when the box section 34 is collapsed. This is particularly advantageous for the ready-to-sell condition of the packaging unit, since any superordinate packaging in the form of a folding box, if present, can be very small.

In a further embodiment, which leads to a particularly simple production of the second partial packaging 22, it is provided to cut and manufacture the second partial packaging 22 from a layer of foldable material, in particular cardboard boxes. The development of such a layer for the exemplary embodiment from FIGS. 8 and 9 is shown in FIG. 10. The development is divided particularly cleverly in that the sections 30, 28, 35, 29, 37, 37, 36, 28 follow one another. The repetition of section 37 makes it possible to overlay the layers 28, 28.

In order to ensure easy foldability and, if necessary, to avoid tearing open the surface of the second partial packaging 22, one edge of the second partial packaging 22 is provided with one or more elongated holes between the section 28 and a bent section, preferably arranged at right angles. The ratio of full to open space is 3: 1 to 1: 3, preferably 1: 1. In a preferred embodiment, exactly two elongated holes are provided here.

The configuration of the second partial packaging 22 is not limited to the exemplary embodiment shown in FIG. 8 and in FIG. 9. For example, it can also be provided that the second partial packaging 22 has a clamping bracket 38, which is connected via a connecting part 39 to the section 28 forming the flat cover over the opening 24 of the first partial packaging 21. The second partial packaging 22 is then through the clamp 38 on the first partial packaging 21 can be fixed and ensures the centering of the section 28 and thus possibly the dispensing device 26 (FIG. 11).

Depending on the field of application, the second partial packaging 22 can be made of different materials. Examples of this are cardboard, corrugated cardboard or plastic. The dimensions of the second partial packaging 22 are largely arbitrary. A preferred dimension is 150mm * 80mm (length * width).

A number of options are provided for the configuration of the dispensing device 26 and the reservoir 27. In a preferred embodiment, a

Dispensing device 26 with a product component 4 contained

Reservoir 27 provided (Fig. 3, 6). The reservoir 27 has an opening 3 which, when the second partial packaging 22 is not activated, has an opening 3

Sealing film 25 is closed. To dispense the product component 4, only a pressure on the upper part 1 of the reservoir 27 is required. The pressure is applied to the product component 4 located in the reservoir 27

Transfer sealing film as sealing film 5, which is broken due to the pressure load. As a result, the product component 4 is released and first falls through the opening 3 of the reservoir 27 and then through the opening 24 of the first partial packaging 21.

In the present case, this is particularly advantageous in the case of the above-mentioned clamp fastening of the dispensing device 26 between two parallel layers 28, 28 lying one on top of the other. The upper part 1 can consist of PVC, PP, PET, PS and / or a combination of these components. The sealing film 5 consists essentially of aluminum, preferably with a plastic coating as the sealing medium. The force required to pierce the sealing film is preferably 15 N (DIN 53142).

The product components provided in the two partial packs 21, 22 can take various configurations. The one in the second The partial packaging 22 provided product component 4 is lumpy, powdery, liquid, pasty or gel-like, in a preferred embodiment lumpy or powdery, while the product component provided in the first partial packaging 21 is liquid or gel-like. In a special embodiment, the lumpy product component 4 is designed to be rotationally symmetrical, in particular lenticular, spherical, elipsoidal or cylindrical with rounded end faces.

The strength (breaking hardness) of the lumpy product component 4 is from 50 N to 120 N and a pressing force from 2 kN to 4 kN. The weight of the lumpy product component 4 is preferably between 200 to 600 mg. The size of a spherical, lumpy product component 4 is provided with a diameter of 5 to 10 millimeters.

It is important here that, in order to achieve the ready-to-use state, the second partial packaging 22 is placed on the delivery side above an opening 24 of the first partial packaging 21, the product component is conveyed from the second partial packaging 22 into the first partial packaging 21 without direct contact with this product component, and both product components in the first partial packaging 21 to be mixed into the finished product.

In a preferred embodiment, it is provided that the two partial packs 21, 22 are separated after the addition of the product components, the separation process corresponding to the reaction time of the product components. The separation process takes from 0.2 to 30 seconds, preferably 15 seconds.

The packaging unit described above serves as packaging for finished cosmetic products, in particular hair colors, hair tints, care products or the like.
